Abstract :
Emaps, a comprehensive environment for displaying geographic data, written in object-oriented Common Lisp and running on a Macintosh computer, is described. In Emaps, a hierarchy of objects-windows, maps, cells-takes advantage of the class-instance inheritance and generic methods of Common Lisp to allow prototyping and exploring of variations. The combination of a class library of objects, a protocol for accessing them, ready access to the full display capabilities of the computer, and the interpreted nature of Lisp make for an interactive environment for visualizing landscapes and exploring geographic information.<>
